VPN (Virtual Private Network) is a network technology concept that uses a public or private network to establish a secure computer network data connection. In this case, the most commonly used public network is the Internet, while private networks are usually leased lines from service providers. It works on layers 2 and 3 of the OSI layer, although the Multi-Protocol Label Switching (MPLS) functionality makes the two layers less different.
An Ivacy virtual private network (in the Korean language it is written as Ivacy 가상 사설망) connects remote locations at different distances in a similar way to a Wide Area Network (WAN). The daily growing customer information base has brought with it the need to expand internal networks beyond their local reach to enable information dissemination and communication. Companies with offices and offices outside the same geographic area will benefit the most from this technology.

Why VPN Service?
Today’s computing environment carries a high and concentrated risk of being compromised by countries that do not have access to it. This fear of a possible invasion of privacy has led people to take precautions when accessing remote services. There are several things that need to choose to make use of a VPN service are:
Avoiding Geographical Restrictions on the Internet:
Some organizations may restrict access to their Internet services to people in certain geographic areas. Several factors that can influence this include licensing issues. Using a VPN service makes it appear as if one is in the same geographic area as the server location.
This prevents data from falling into unintended hands and thereby violating its confidentiality. VPN services encrypt data with the help of encryption protocols and thus represent the most important pillars of data confidentiality, namely achieving confidentiality, integrity, and availability.
Avoid Government Censorship:
VPN services allow users to bypass the restrictions imposed by different governments in their home country in accessing different websites.
